Predictors of length of postoperative stay following endoscopic skull base surgery with intraoperative CSF leak.
Establishing benchmarks for length of stay (LOS) may inform strategies to improve resource efficiency, decrease costs, and advance care quality. In this study, the authors characterize postoperative LOS in endoscopic skull base surgery (ESBS) and elucidate prolonging factors. ⋯ With healthcare utilization receiving increased attention, mitigating factors that extend LOS are important. Extent of surgery and certain postoperative complications may constitute key factors prolonging LOS following intradural ESBS with intraoperative CSF leak.

Stereotactic radiosurgery for anterior cranial fossa dural arteriovenous fistulas.
Anterior cranial fossa (ACF) dural arteriovenous fistulas (DAVFs) are notoriously malignant vascular abnormalities, and their drainage into the cortical vein poses a high risk of intracranial hemorrhage (ICH). Stereotactic radiosurgery (SRS) is increasingly seen as an alternative to microsurgery or embolization for the treatment of DAVFs; however, researchers have yet to report on its applicability to ACF DAVFs. This paper summarizes the authors' experience in the use of SRS for ACF DAVFs. The authors' objective was to gain a preliminary overview of SRS outcomes in the treatment of ACF DAVFs. ⋯ SRS appears to be a viable alternative treatment for ACF DAVFs, particularly for patients who are not suitable candidates for surgery or those with an unfavorable angioarchitecture.

The oculomotor cistern and pituitary adenomas: anatomical and clinical study.
The oculomotor cistern (OMC) is a meningeal cuff filled with CSF that contains the oculomotor nerve (cranial nerve [CN] III) at the level of the lateral wall of the cavernous sinus. Only a few studies have investigated the involvement of the OMC by pituitary adenomas (pituitary neuroendocrine tumors [PitNETs]), mainly with relatively small case series. The aim of this study was to perform a histomorphological description of the OMC and systematically analyze its involvement by PitNETs from radiological, clinical, and surgical perspectives. ⋯ Significant OMC involvement by PitNETs might be underrecognized, but it can be treated using the endoscopic transsphenoidal approach, and it affects patient outcomes.

A management algorithm for idiopathic intracranial hypertension in skull base meningoencephaloceles.
In this study, the authors assessed an algorithm for the diagnosis and management of idiopathic intracranial hypertension (IIH) in patients who had undergone surgical repair of skull base meningoencephaloceles presenting with spontaneous cerebrospinal fluid (sCSF) leakage. ⋯ Utilizing an algorithm of direct meningoencephalocele repair and selective shunting, acute and remote CSF leak recurrence rates were each 3.8%, and the VPS rate was 15.0%. These data provide further insight into CSF dynamics in this population and argue against the theoretical concern that CSF pressure will increase postrepair. Significant intraindividual variability suggests multiple LPs may be necessary before committing to invasive IIH treatment. Further work is necessary to determine the optimal IIH management strategy.
